Checks, Please

"Think of your nails as an accessory," says Jan Arnold, cofounder of CND, whose technicians created the high-contrast nails at Nicole Miller. "You pick out earrings, necklaces, rings, and hats to complement your style every day.

Why not polish?" Get your nails set for summer with these bold and bright ideas. To section your nails into perfect quadrants, draw a cross on each nail with an ultrafine eyeliner brush and a dark blue polish. (Make sure to keep your nail brushes away from your regular makeup brushes!) Next, use a regular nail polish brush to fill in from the corners. Says Arnold, "If a girl can figure out how to put on eyeliner, she can do this nail."
